Abstract:
Shields for feedthrough pin insulators of a hot cathode ionization gauge are provided to increase the operational lifetime of the ionization gauge in harmful process environments. Various shield materials, designs, and configurations may be employed depending on the gauge design and other factors. In one embodiment, the shields may include apertures through which to insert feedthrough pins and spacers to provide an optimal distance between the shields and the feedthrough pin insulators before the shields are attached to the gauge. The shields may further include tabs used to attach the shields to components of the gauge, such as the gauge's feedthrough pins. Through use of example embodiments of the insulator shields, the life of the ionization gauge is extended by preventing gaseous products from a process in a vacuum chamber or material sputtered from the ionization gauge from depositing on the feedthrough pin insulators and causing electrical leakage from the gauge's electrodes.

AN ELECTRON SHIELD FOR A SHADOW-MASK TYPE OF COLOR TUBE BRIDGES THE SPACE BETWEEN THE MASK FRAME AND THE TUBE ENVELOPE. THE ELECTRON SHIELD IS COMPRISED OF A PLURALITY OF SEGMENTS EACH SEGMENT HAVING ONE END WHICH IS CURVED TO CONFORM TO THE INSIDE CONTOUR OF THE ENVELOPE CORNER IN WHICH IT IS PLACED. THE OTHER END OF EACH SHIELD SEGMENT IS STRAIGHT AND SLIGHTLY OVERLAPS THE CURVED END OF THE PREVIOUSLY PLACED SEGMENT.
Abstract:
In order to improve the decoupling efficiency in a top-emitting OLED a top-emitting electroluminescent component (100) is suggested comprising a substrate, a first electrode (120) nearest to the substrate, a second electrode (14) located at a distance from the substrate, and at least one light-emitting organic layer (130) arranged between both electrodes, the emitted light being transmitted through the second electrode. The component in accordance with the invention is distinguished by an additional layer (150) facing away from the at least one organic layer is arranged on the side of the second electrode, which additional layer comprises optically effective light-emitting heterogeneities (151, 152, 153), especially in the form of scatter centers, the degree of transmission of the additional layer of the emitted light being greater than 0.6. This additional layer can be applied by various wet-chemical processes and vacuum methods, the inhomogeneities being introduced into and/or applied onto the decoupling additional layer during or after the application process. Furthermore, the invention also relates to a method for producing such a component.

Abstract:
A passive matrix in-plane switching bi-stable display (1) has first and second electrodes (20, 30), and pixels (10) associated with intersections of the first electrodes (20) and the second electrodes (30). The display (1) comprises on a same substrate both the first electrodes (20) and, per pixel (10), a first group of electrodes (G1) interleaving with a second group of electrodes (G2). The electrodes of the first and second group (G1, G2) extend in a same first direction, and are displaced with respect to each other in the first direction to obtain in the first direction a first area (A1) where only electrodes of said first group (G1) are present, a second area (A2) where only electrodes of said second group (G2) are present, and a third area (A3) in-between the first and the second area (A1, A2) where both electrodes of said first and second group (G1, G2) are present. Insulating areas (40) are present at least at crossing positions where the second electrodes (30) have to cross the first electrodes (20). The second electrodes (30) extend in a second direction and are positioned for crossing the first electrodes (20) at the crossing positions and for contacting the second group of electrodes (G2) in the second area (A2). Sub-electrodes (S1) per pixel (10) are arranged in the second direction to interconnect the first group of electrodes (G1) in the first area and to connect said first group (G1) to an associated one of the first electrodes (20).
Abstract:
An electroluminescence device having enhanced overall luminescence or brightness resulting from a plurality of luminescence groups arranged in a stacked configuration, such that the luminescence output from one luminescent group is caused to blend with the luminescent output from one or more additional luminescent groups to provide an improved luminescence output that enhances the intensity of the overall luminescence generated by the device as compared to a device with a single luminescent group, or electrode assembly containing such. In some aspects, the improvement or increase may be at least additive, and in some cases synergistic. The device can include a multi-layer diamond electroluminescence device configured to provide enhanced luminescence intensity, wherein the device comprises a plurality of operating pairs of electrode layers; at least one diamond-like carbon layer disposed between each of the operating pairs of electrode layers, and electrically coupled to an electrode layer within a respective pair of electrode layers; and at least one luminescent layer disposed between each of the operating pairs of electrode layers, and electrically coupled to the diamond-like carbon layer and the respective pair of electrode layers, such that upon receiving electrons from the diamond-like carbon layer the luminescent layer illuminates.
Abstract:
A field emission display device includes three parts: a cathode emitter unit, an electron amplification unit, and a faceplate unit. The primary emission of electrons emitted from the cathode emitter unit bombards an electrode layer that includes an electron amplification material in order to generate secondary emissions of electrons. The secondary emissions of electrons bombard a light-emitting layer of the faceplate unit to generate fluorescence. Then, the fluorescence is transmitted through a transparent faceplate for viewing.

A light emission device has an emitter made of a dielectric material, a cathode electrode disposed on a surface of the emitter, an anode electrode disposed on a reverse surface of the emitter, and a pulse generation source for applying a drive voltage between the cathode electrode and the anode electrode through a resistor. A fluorescent body is disposed on the surface of the emitter out of contact with the cathode, but as closely to the cathode electrode as possible.
